The video is great but it sounded like there was still some noise coming
from the timing assembly was the vanos assembly also needing attention? or
is this a non- vanos engine it looked like an m62tu to me
+Donovan Petersen I know your comment is old, but here is my reply anyway: It is a non-VANOS engine so a non TU motor. 4 things are a dead give away. 1- the intake runners are larger than a TU/VANOS engine. 2- the intake tube going from the air filter to the engine is aluminum, TU engines use plastic all the way to the TB. 3- Idle Air Controller is visible above the TB. 4- no VANOS solenoids on the upper timing cover. I'm tackling this job on my car as I write this and I have the TU/VANOS version (99 iL). I've watched countless videos, read every post I can find and have studied the details religiously. I know I can do the job, but I'm fearing that I will mess up the VANOS timing and make matters worse and get stranded on the highway in the middle of nowhere.
Tony,
This is a great video. It clearly explains what to do. However, I've heard
there is a big problem to undoing the main crank bolt. Did you use an air
tool or a very long wrench? Your numbers for the repair seem about right. I
guess an amateur would take about 40 hours.
Did you find any loose bolts on the oil pump which is another known problem?
Keep up the good work.

+BloodScatter The BMW 2.8l is an inline 6 engine with a timing chain between the crankshaft and one camshaft and another short chain between the 2 camshafts. The simpler routing of the chain makes this failure less common but still possible.
